I would like to replace my stock water neck with a chrome one but I have a sensor stuck in the stock neck. I was told it was an emissions sensor and since I have all my emissions stuff removed its no big deal to leave off but when I discount it the temp gauge stops working. I have a stock electric fan so I also have a sensor in both heads, what’s going on? I have seen a thread about a small flat temp sensor that would fit under the water neck anyone know? Can I remove a sensor or do I need all three? :confused:
